<p><b>Kyoto, Japan</b> - The past week has seen a number of new twists in the tale of a prominent Japanese cardiologist accused of fabricating and manipulating data and images for cardiology research later published in a range of cardiology journals.</p>
<p>Last year, the <b>American Heart Association </b>(AHA) issued a <a href="http://www.theheart.org/article/viewDocument.do?document=http%3A%2F%2Fwww.theheart.org%2FviewDocument.do%3Fdocument%3Dhttp%253A%252F%252Fhyper.ahajournals.org%252Fcontent%252Fearly%252F2012%252F03%252F09%252FHYP.0b013e31824c1097.full.pdf%252Bhtml%253Fpapetoc" target="_blank" name="">notice of concern</a> about <a href="http://www.theheart.org/article/viewDocument.do?document=http%3A%2F%2Fwww.theheart.org%2Farticle%2F1368885.do" target="_blank" name="">five papers appearing in three AHA-published journals</a>—<i>Circulation</i>, <i>Circulation Research, </i>and<i>Hypertension</i><i>—</i>between 2001 and 2004, as reported by <a href="http://www.theheart.org/article/viewDocument.do?document=http%3A%2F%2Fwww.theheart.org%2Fsection%2Fheartwire.do" target="_blank" name="">heartwire</a>.</p>

<p>Concerns about <b>Dr Hiroaki Ma</b><b>t</b><b>subara</b> ultimately spread to the <a href="http://www.theheart.org/article/viewDocument.do?document=http%3A%2F%2Fwww.theheart.org%2Farticle%2F997973.do" target="_blank" name="">Kyoto Heart Study</a>, the &gt;3000 patient, postmarketing study Matsubara presented to some fanfare at the <b>E</b><b>uropean </b><b>S</b><b>ociety of </b><b>C</b><b>ardiology</b> <b>2009 </b><b>Congress</b> and subsequently published in the <i>European Heart Journal</i>(<i>EHJ</i>). The <i>EHJ</i> later retracted that article, a move the AHA opted to follow this May after concluding its review of the studies published in a number of the association&#8217;s journals. Matsubara resigned from his post at Kyoto Prefectural University earlier this year.</p>
<p>Last Friday, Japan&#8217;s minister of health, <b>Norihisa Tamura</b>, as well as university officials at Kyoto Prefectural University announced that the Kyoto Heart Study data were &#8220;very likely&#8221; fabricated, according to <a href="http://www.theheart.org/article/viewDocument.do?document=http%3A%2F%2Fwww.google.com%2Fhostednews%2Fafp%2Farticle%2FALeqM5i4BcekZkUxY8KOaZHY5CKcLRCaHA%3FdocId%3DCNG.a545f6b10dd242f146be42fe56cdd915.d1" target="_blank" name="">AFP</a>. &#8220;Incomplete&#8221; patient data were used in the study, which concluded the blood-pressure drug could also reduce other cardiovascular end points via mechanisms <a href="http://www.theheart.org/article/viewDocument.do?document=http%3A%2F%2Fwww.theheart.org%2Farticle%2F1117633.do" target="_blank" name="">unrelated to blood-pressure lowering</a>. Had &#8220;complete patient records&#8221; been used, the study would have reached &#8220;a different conclusion,&#8221; the university concluded.</p>
<p>Finally, it has also emerged that two Novartis employees were involved in the conduct and analysis of the Kyoto Heart Study and a second investigator-initiated trial, the <a href="http://www.theheart.org/article/viewDocument.do?document=http%3A%2F%2Fwww.theheart.org%2Farticle%2F1117633.do" target="_blank" name="">Jikei Heart study</a>, although their participation was not acknowledged in publications and presentations of the data. Those employees are no longer with Novartis.</p>
<p>Novartis has <a href="http://www.theheart.org/article/viewDocument.do?document=http%3A%2F%2Fwww.novartis.com%2Fnewsroom%2Fproduct-related-info-center%2Fvalsartan-investigator-initiated-trials-in-japan.shtml" target="_blank" name="">issued a statement</a> saying that it had launched a third-party investigation into allegations of conflict of interest (COI) relating to the two Novartis employees back in April.</p>
<p>&#8220;At the time these Japanese valsartan [investigator-initiated trials] IITs started between 2001 and 2004, there were no specific guidelines for COI in IITs,&#8221; the statement reads. &#8220;The former employees and their managers misunderstood the appropriate level of involvement in IITs of employees of a pharmaceutical company. However, there are now COI guidelines for in place across the industry, which are followed by all Novartis Pharma Japan employees.&#8221;</p>
<p>In June, after its investigation concluded, the company implemented &#8220;preventive and corrective measures . . . to address the causes identified in the third-party investigation, demonstrating our social and ethical accountability,&#8221; the statement notes.</p>
<p>According to AFP, Novartis has also stressed that the university &#8220;was not able to conclude that there was intentional wrongdoing&#8221; and that it remains possible that the &#8220;inconsistencies&#8221; may have been unintentional.</p>

<p>노바티스 직원, 디오반 효능 조작 관여 탄로<br />
코메디닷컴 2013.07.30 10:57 수정 2013.07.31 16:56<br />
<a href="http://www.kormedi.com/news/article/1207334_2892.html">http://www.kormedi.com/news/article/1207334_2892.html</a></p>
<p>최근 글로벌 제약사 노바티스 직원이 일본의 저명한 심장병 전문의 마쓰바라 히로아키 교수의 임상 데이터 조작 사건에 연루된 것으로 알려지면서 파장이 커지고 있다고 의학정보사이트 ‘The Heart Org’는 지난 19일 보도했다.</p>
<p>미국심장학회(AHA, American Heart Association)는 지난 2001년부터 2004년까지 학회가 발행하는 3개 저널(Circulation, Circulation Research, Hypertension)에 실린 마쓰바라 교수의 논문(5편)이 임상 데이터와 이미지의 조작과 관련이 있다며 우려를 표명해 왔다.</p>
<p>유럽심장학회지(EHJ)는 마쓰바라 교수가 유럽심장학회(2009년) 회의에서 발표하고 이 저널에 게재한 고혈압 치료제 디오반(성분명: 발사르탄)의 ‘시판 후 연구’ 등의 논문을 이미 철회한 바 있다. 이어 AHA도 논란 끝에 여러 저널에 실린 마쓰바라 교수의 논문들을 지난 5월에 취소키로 결정했다.</p>
<p>마쓰바라 교수의 연구결과에 대한 이같은 우려는 일본 내에서도 증폭되고 있다. AFP통신에 따르면 지난 26일 교토 부립의과대학(KPUM)측과 일본 후생노동성이 마쓰바라 교수의 ‘교토 심장 연구(Kyoto Heart Study)&#8217; 자료가 조작됐을 가능성이 매우 높다고 발표했다.</p>
<p>이 연구는 불완전한 환자 자료를 인용해 혈압약인 ‘디오반’이 혈압강하와 관련 없는 기전으로 다른 심혈관 질환에서 효과를 보였다고 발표한 바 있다. KPUM은 “이 논문이 온전한 환자 자료를 사용했다면 다른 결론을 내렸을 것”이라고 밝혔다.</p>
<p>대학 측은 또 데이터에 문제가 있었던 만큼 디오반이 다른 혈압약에 비해 뇌졸중, 협심증 등을 줄이는 효과가 있다는 연구진의 결론에는 오류가 있을 가능성이 크다고 밝혔다.</p>
<p>더욱 논란이 일고 있는 것은 2명의 노바티스 직원이 ‘교토 심장 연구’와 연구자 주도 임상시험(이하 IIT)인 ‘지케이 심장 연구(Jikei Heart Study)’의 실행과 분석에 관여했다는 사실이 드러난 것이다. 이들은 그럼에도 논문 출판과 발표에 연구 참여자로 공식 참여하지 않아 논란의 소지를 제공했다. 이들 직원은 현재 노바티스를 퇴사한 상태이다.</p>
<p>노바티스는 이번 논란과 관련해 제3의 기관에 의해 지난 4월부터 조사에 착수했다는 성명서를 발표하기도 했다.</p>
<p>노바티스는 “지난 2001년부터 2004년 사이 일본에서 디오반(성분명:발사르탄) IIT가 시작될 무렵, IIT의 이해충돌(COI) 관련해 구체적인 가이드라인이 존재하지 않았다”고 밝히며 “제약회사의 직원들이 어느 선까지 IIT에 관여하는 게 적절한가에 대한 이해가 부족했다”고 전했다. 이어 “현재는 업계 전반에 걸쳐 COI 가이드라인이 자리를 잡았으며, 모든 노바티스의 일본 직원들은 이를 잘 따르고 있다”고 말했다.</p>

<p>日, 의대서 혈압강하제 임상 데이터 조작 파문</p>

<a href="http://news.khan.co.kr/kh_news/khan_art_view.html?artid=201307311135041&amp;code=970203">http://news.khan.co.kr/kh_news/khan_art_view.html?artid=201307311135041&amp;code=970203</a></p>
<p>스위스 제약사 노바티스의 일본법인이 취급하는 고혈압 치료제 디오반에 대해 일본의 의과대학이 실시한 임상연구 데이터가 인위적으로 조작된 것으로 드러났다.</p>
<p>도쿄 지케이카이(滋惠會)의대 조사위원회는 30일 이 대학 연구팀이 실행한 혈압강하제 디오반(성분 발사르탄) 임상 연구 논문에서 “노바티스 전 직원의 관여 등을 통해 데이터가 인위적으로 조작된 사실이 인정돼 논문을 철회키로 했다”고 발표했다. 지케이카이 의대조사에 따르면 대학이 보유하고 있는 671인분의 데이터와 최종통계를 비교한 결과 86건에서 혈압치가 다른 것으로 나타났다. 다만, 조작은 통계해석의 단계에서 벌어진 것으로 보여 “대학의 연구자가 간여한 것이 아니라 노바티스의 전 사원이 조작했다”고 대학측은 판단했다.</p>
<p>지케이카이 대학의 임상연구는 고혈압 환자 3081명을 대상으로 실시돼 디오반이 뇌졸중과 협심증을 예방하는 데 효과가 높다는 논문을 2007년 이 대학 연구진이 영국 의학지에 발표하기도 했으나 대학측은 데이터 조작이 밝혀짐에 따라 논문을 철회하기로 했다.</p>
<p>일본에서 디오반 임상연구는 지케이카이 의대, 교토(京都)부립 의과대학, 나고야(名古屋)대, 지바(千葉)대 등 5개 대학에서 실시됐으며 지케이카이 의대와 교토부립 의대의 연구 논문을 노바티스측이 홍보에 사용해 왔다. 디오반은 세계 판매량 1위의 혈압강하제다.</p>
<p>앞서 교토부립 의대도 지난 11일 이 대학의 마쓰바라 히로아키(松原弘明) 전 교수가 실시한 디오반 임상 연구에서 데이터 조작이 이뤄진 것으로 드러나 파문을 일으켰다. 노바스티측은 교토부립 의대 연구에 자사 직원을 참가시키고 연구진에 1억엔 규모의 기부금을 제공한 것으로 알려졌다.</p>

<p>Hiroaki Matsubara</p>
<p>The American Heart Association, which publishes a number of journals, has issued an Expression of Concern about five papers in three of their publications, following allegations of image manipulation. All of the papers include <a href="http://www.f.kpu-m.ac.jp/j/english/modules/ct/index.php?content_id=57"><span style="color: #004477;">Hiroaki Matsubara</span></a>, of Kyoto Prefectural University, as a co-author.</p>
<p>The <a href="http://hyper.ahajournals.org/content/early/2012/03/09/HYP.0b013e31824c1097.full.pdf+html?papetoc"><span style="color: #004477;">notice</span></a> begins:</p>
<blockquote><p>It has come to the attention of the American Heart Association (AHA), in a public manner, that there are questions concerning a number of figures in several AHA journals’ articles…</p></blockquote>
<p>The “public manner” was three posts last year on the Abnormal Science blog, available <a href="http://abnormalscienceblog.wordpress.com/2011/11/27/matsubara-lab-in-japan-breathtaking-reuse-of-western-and-northern-blot-bands/"><span style="color: #004477;">here</span></a>,<a href="http://abnormalscienceblog.wordpress.com/2011/11/30/matsubara-lab-in-japan-breathtaking-reuse-of-histological-images-and-fragments-part-2/"><span style="color: #004477;">here</span></a> and <a href="http://abnormalscienceblog.wordpress.com/2011/12/14/matsubara-lab-in-japan-anything-goes-part-3/"><span style="color: #004477;">here</span></a>, alleging that images were manipulated in the manuscripts, and that histology slides were reused.</p>
<p>The notice continues: <a href="http://retractionwatch.wordpress.com/2012/03/13/five-papers-by-prominent-cardiologist-hiroaki-matsubara-subject-to-expression-of-concern/#more-6846"><span style="color: #004477;">Read the rest of this entry »</span></a></p>

Matsubara’s institution, Kyoto Prefectural University, <a href="http://retractionwatch.wordpress.com/2012/03/13/five-papers-by-prominent-cardiologist-hiroaki-matsubara-subject-to-expression-of-concern/"><span style="color: #004477;">confirmed to us last March</span></a> that it was investigating the prominent cardiologist.</p>
<p>The work of Matsubara came into question last year when the American Heart Association issued an expression of concern for <a href="http://retractionwatch.wordpress.com/2012/03/13/five-papers-by-prominent-cardiologist-hiroaki-matsubara-subject-to-expression-of-concern/"><span style="color: #004477;">five papers</span></a> the society published in its journals.
